Gytc8AS Figure 8 Fiber Optic Cable
Gytc8AS Figure 8 Fiber Optic Cable 2-144 Core PE jacket SM armoured Overhead Self-supporting Outdoor networking
Figure 8 fiber optic cable is constructed by placing a single-mode or multi-mode fiber into a loose sleeve made of high modulus plastic and filled with a water-blocking compound. The center of the core is a metal reinforcement core, and for some cores, a layer of polyethylene is extruded over the metal reinforcement core. The loose tubing (and filler rope) is twisted around the center reinforcement core to form acompact
and round core, with the gapsin the corefilled with a water-blocking filler. The cable core is wrapped longitudinally with steel-plastic composite tape and placed in parallel with the steel strand while squeezing the 8-letter sheath into the cable.
Product Features:
- Precise control of the residual length of the fiber, which ensures that the fiber optic cable has good tensile properties and temperature characteristics;
•Loose casing material itself has good hydrolysis resistance and high strength, and the tube is filled with special oil paste, which is a key protection for optical fiber;
• No need to put steel strand when erecting, which increases the construction speed by 3-4 times and reduces the installation cost;
• Good waterproof performance of fiber optic cable:
1. Single steel wire center reinforcement,
- loose casing filled with special oil paste,
- 100% cable core filling,
- double-sided plastic coated steel tape (PSP/APL) to improve the cable’s moisture-proof ability,
- good water-blocking materials to prevent longitudinal seepage of optical cable.
